Dear group,
I tried to simplify an awkward looking integral with "Mathematica 7"
using its "(Full)Simplify[...]" function. Unfortunately it failed to do
so, even though I know that this would be possible. I boiled down the
problem to the following very simple example ("f" is just a generic,
undefined function): The input
Integrate[2 f[x], {x, 0, 1}]/2 // FullSimplify
returns just the input
Integrate[2 f[x], {x, 0, 1}]/2
(same result for "Simplify" instead of "FullSimplify"), i.e.,
Mathematica seems not to be aware that the factor "2" can be canceled
out. Even worse, the expressions
TrueQ[Integrate[2 f[x], {x, 0, 1}]/2 == Integrate[f[x], {x, 0,
1}]]
SameQ[Integrate[2 f[x], {x, 0, 1}]/2 , Integrate[f[x], {x, 0, 1}]]
Integrate[2 f[x], {x, 0, 1}]/2 === Integrate[f[x], {x, 0, 1}]
return the (wrong) result "False".
So my question: Is there something I am overlooking, or what is the
right "Mathematica" way to treat expressions like the one above.
Thanks a lot in advance,
Klaus
